Usage
Your impact tool generates the following output torque:
Cat # Ft.-Lbs. (Nm)
DW292 345 (468)
DW293 345 (468)
DW294 345 (468)
CAUTION: Ensure fastener and/or system will withstand the level
of torque generated by the tool. Excessive torque may cause break-
age and possible personal injury.
1. Place the socket on the fastener head. Keep the tool pointed
straight at the fastener.
2. Press rocker switch to start operation. Always check torque with
a torque wrench, as the fastening torque is affected by many
factors including the following:
• Voltage: Low voltage, due to generator or long extension
cord, will reduce fastening torque.
• Socket size: Failure to use the correct socket size will cause
a reduction in fastening torque.
• Bolt Size: Larger bolt diameters generally require higher
fastening torque. Fastening torque will also vary according to
length, grade, and torque coefficient.
• Bolt: Ensure that all threads are free of rust and other debris
to allow proper fastening torque
• Material: The type of material and surface finish of the
material will affect fastening torque.
• Fastening Time: Longer fasten ing time results in increased
fastening torque. Using a longer fastening time than recom-
mended could cause the fasteners to be overstressed,
stripped or damaged.
Capacity
Your 1/2" (13 mm) impact wrench uses sockets with 1/2" square
drive ends. A 3/4" (19 mm) impact wrench uses sockets with 3/4"
square drive ends. Both sizes of impact wrenches are capable of
driving the same range of hex impact sockets available.
In particularly heavy duty usage the 3/4" drive impact wrench has
an extra strong anvil that will resist breakage.
MAINTENANCE
Your D WALT power tool has been designed to operate over a
E
long period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and regular
cleaning.
WARNING: To reduce the risk of injury, turn unit off and
disconnect tool from power source before installing and removing
accessories, before making any adjustments or removing/installing
attachments or accessories.
Lubrication
Your tool was properly lubricated before leaving the factory. In
two to six months, depending upon use, take or send the tool to a
certified service center for a thorough cleaning and inspection. This
lubrication should only be attempted by trained power tool repair
persons, such as those at D WALT service centers or by other
E
qualified service personnel.
Tools used constantly on production or heavy duty jobs or exposed
to heat may require more frequent lubrication. Tools "out of service"
for long periods should be relubricated before being put back into
service.
Cleaning
WARNING: Blow dirt and dust out of the main housing with dry
air as often as dirt is seen collecting in and around the air vents.
Wear approved eye protection and approved dust mask when
performing this procedure.
WARNING: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. These chemicals may
weaken the materials used in these parts. Use a cloth dampened
